Microbes account for more than 90% of ocean biomass and constitute a hidden majority of life that flourishes in the sea. This site contains a variety of educational and supporting materials for students and teachers of microbiology. You will find information about microorganisms, extremophiles and extreme habitats, as well as links to online resources, teaching and learning activities.

Microfossils are microscopic single-celled organisms that belong to the Kingdom Protista (or Protoctista). Examples include calcareous nannofossils, foraminifera, diatoms, radiolarians, and silicoflagellates; planktonic organisms that inhabit the sunlit surface waters of the world ocean. The tiny shells of microfossils contribute to the sediments that cover vast areas of the seafloor. This website has a poster (pdf) which shows several different images of microfossils, taken through microscopes, as well as activities for students (pdf) simulate the identification and use of these microfossils to examine past climate change and Earth history. Activities include: Small Creatures-Big Science, Secrets of the Sediments, Nannofossils Reveal Seafloor Spreading Truth.

The North Atlantic Oscillation (NAO) may pale against El Nino's press, but this climate pattern can kick up a commotion all over the Northern Hemisphere. Lately, scientists have been discovering why. This four-part story describes the NAO, how it "does its thing," how data are "hunted and gathered," and NAO forecasting efforts. Grade level: 9-College. LINK >>

This interactive learning demo includes two videos (ocean energy sources and global impacts) and supplementary resources. The ocean energy sources described and explained are tidal energy, ocean thermal energy conversion, and wave energy. Oil, natural gas, and methane hydrates are non-renewable but potent fossil fuels that lie buried in sea-floor sediments. There are two activities included with this learning resource: ocean thermal energy and methane hydrates. [Source: NOAA Multimedia Learning Objects] Grade level: 5-College. LINK >>

Dr. Martin Visbeck's online slide show about the North Atlantic Oscillation (NAO) is intended for older high school or undergraduate audiences. It gives background on the NAO, its impacts (temperature, precipitation, storminess, economics), its effects on the North Atlantic Ocean, the stratosphere, and global warming. Grade level: 10-College. LINK >>
